因为我是Angular的新手，任何人都可以提供一个简单的解决方案，使用angular 2加载JSON文件数据。
我的代码如下
的index.html
<html>
<head>
<title>Angular 2 QuickStart</title>
<Meta charset="UTF-8">
<Meta name="viewport" content="width=device-width,initial-scale=1">
<link rel="stylesheet" href="css/styles.css">
<!-- 1. Load libraries -->
<!-- Polyfill(s) for older browsers -->
<script src="node_modules/core-js/client/shim.min.js"></script>
<script src="node_modules/zone.js/dist/zone.js"></script>
<script src="node_modules/reflect-Metadata/Reflect.js"></script>
<script src="node_modules/systemjs/dist/system.src.js"></script>
<!-- 2. Configure SystemJS -->
<script src="systemjs.config.js"></script>
<script>
System.import('app').catch(function(err){ console.error(err); });
</script>
</head>
<!-- 3. Display the application -->
<body>
<my-app>Loading...</my-app>
</body>
</html>
app.component.ts
import {Component} from '@angular/core';
@Component({
selector: 'my-app',template: `
<div id="main">
Main Div
<div id = "header"></div>
<div id = "content">
<ul class="games">
<li>
</li>
</ul>
</div>
</div>
`
})
export class AppComponent {
}
games.json
{
"games":[
{
"title":"Primary Operations","enabled":true
},{
"title":"Curated Games","enabled":false
}
]
}
我想从app.component.ts获取所有来自games.json的游戏到li
请详细说明。

以下是我解析JSON的代码的一部分，它可能对您有所帮助：
原文链接：https://www.f2er.com/angularjs/143977.htmlimport { Component,Input } from '@angular/core';
import { Injectable } from '@angular/core';
import { Http,Response,Headers,RequestOptions } from '@angular/http';
import {Observable} from 'rxjs/Rx';
import 'rxjs/add/operator/map';
import 'rxjs/add/operator/catch';
@Injectable()
export class AppServices{
constructor(private http: Http) {
var obj;
this.getJSON().subscribe(data => obj=data,error => console.log(error));
}
public getJSON(): Observable<any> {
return this.http.get("./file.json")
.map((res:any) => res.json())
.catch((error:any) => console.log(error));
}
}
